Atmospheric pressure refers to the force per unit area exerted against a surface by the weight of air above that surface in the Earth's atmosphere. The standard atmosphere (symbol: atm) is a unit of pressure at sea level and is equal to 101325 Pascal.
Isobars - Measure atmospheric pressure Isotherms - Measure temperature Isoheights - Measure elevation
I think you could be referring to a barometer, which measures atmospheric pressure and is an indicator of when it will rain or shine.
Pressure is often measure in units of force per area. In the standard system of units, the SI, that would be Newton / meter2 - this unit is also called Pascal. Other commonly used units are bar (equal 100,000 Pascal), and atmosphere (the atmospheric pressure under standard conditions - close to one bar).
Newtons / square meter. This unit has the special name Pascal.
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
A barometer is an instrument used to measure the atmospheric pressure. It does so by comparing the atmospheric pressure with a predefined standard pressure.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
Pascals measure pressure, which is the force applied to a specific area. It is the standard unit for expressing atmospheric pressure, blood pressure, and other forms of pressure in various systems.
it's the standard pressure at which all pilots set their altimeter, when communicating Fight Levels.
In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.

1013.25 hPa was selected as the standard atmospheric pressure because it is the average pressure at sea level in a region without weather disturbances. It serves as a reference point for comparing and measuring atmospheric pressure changes across different locations and elevations.
Atmospheric pressure is typically measured in units of millibars (mb) or kilopascals (kPa). The standard unit for atmospheric pressure is the pascal (Pa), with 1 atmosphere being approximately 1013.25 hPa or 101.3 kPa.
A pressure gauge or manometer is typically used to measure pressure above atmospheric pressure. These devices can accurately measure the pressure difference between the system being measured and atmospheric pressure.
